\section{Conclusion}
\ourSystem~is an asynchronous replicated storage system with low replication
cost and fast failure recovery. \ourSystem~accomplishes
this by separating data and metadata and replicating metadata on
all replicas, while replicating data on subsets of them.

\ourSystem~demonstrates that full replication of metadata can 1)
ensure that the system works correctly despite partial replication of
data and 2) speed up recovery when replicas fail. The evaluation shows
that \ourSystem~achieves higher throughput and availability than previous
work.
